v2.08.160 firmware - broken launcher

Hi @Gordon - I tried out v2.08.160 last night to try the Bangle.getGPSPower();
However I am now having trouble getting the standard launcher to work.
All I get is a blank screen on BTN2.
When using the tapelauncher I get the following.
The watch can still connect to the IDE but the launch capabilities are broken.
